Greetings to Everyone.

I am having trouble figuring out the proper usage of filter with OnPrem Business Central Api. We have used multi-tenant deployment.

This is working
http://localhost:7048/gasorgn/api/BizNP/biobizapi/v1.0/companies(3530cd87-f0b2-ec11-9111-82e8be684e31)/generalledgerentries?tenant=gasmaster

But while using the filter this way, it is not working
http://localhost:7048/gasorgn/api/BizNP/biobizapi/v1.0/companies(3530cd87-f0b2-ec11-9111-82e8be684e31)/generalledgerentries?$filter=PostingDate eq 2022-03-15?tenant=gasmaster

Likewise, use of expand on standard api also does not work
http://localhost:7048/gasorgn/api/v2.0/companies(3530cd87-f0b2-ec11-9111-82e8be684e31)/customers?$expand=contactsInformation?tenant=gasmaster

They Give the following message

{"error":{"code":"Authentication_InvalidCredentials","message":"Web service call failed because user could not be authenticated or authorized. CorrelationId: ae68c640-ec54-43f2-90b9-27c80fdb1f45."}}

I would be grateful for any help or suggestions.

gt	Greater than	?$filter=unitPrice gt 1000
ge	Greater than or equal	?$filter=unitPrice ge 1000
lt	Less than	?$filter=unitPrice lt 1000
le	Less than or equal	?$filter=unitPrice le 1000
Logical operators
and	Logical and	?$filter=number ge '50000' and number lt '60000'
or	Logical or	?$filter=category eq 'Expense' or category eq 'Income'
not	Logical negation	Not supported
Grouping
()	Precendence grouping	?$filter=(category eq 'Expense' or category eq 'Income') and (number ge '40000' and number lt '50000')
Comparison operators
contains	Search for substring	?$filter=contains(displayName, 'red')
endswith	Test if first string ends with second string	?$filter=endswith(email,'contoso.com')
